It’s too early to know if the deadly mass shooting at a country music festival in Las Vegas that has left at least 50 dead and 200 others injured will spark new calls for gun control. But it's a safe bet as the West Coast wakes to the grim news.

"My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!” the president wrote.

White House Press Secretary Sarah Huckabee Sanders said Trump has been briefed. "We are monitoring the situation closely and offer our full support to state and local officials," she said in a statement. "All of those affected are in our thoughts and prayers.”

Police reported that the suspect, a 64-year-old Nevada resident, is dead. Police said they believe it is a lone wolf attacker.

WHAT WOULD HAVE BEEN THE STORY OF THE DAY

Oh, to be a fly on the wall in the Blue Room on Monday night when Trump is joined by Republican members of Congress for dinner. The gathering comes just a few days after Tom Price, who gave up his seat — and chairmanship of the House Budget Committee to work for Trump — resigned from his post as secretary of Health and Human Services following revelations he had traveled excessively on private jets.

The White House announced the dinner is happening but did not release details on who, specifically, would attend or what is on the agenda. What we do know is that congressional Republicans are in search of a political win, and hope the sweeping tax reform proposal is the thing to deliver one.

More on that below, because the biggest story this weekend had been Trump’s attacks on San Juan Mayor Carmen Yulin Cruz and those he dubbed "politically motivated ingrates" for criticizing the speed and scope of the federal recovery effort on Puerto Rico after Hurricane Maria.

Trump’s Twitter assault, which began early Saturday and lasted through Sunday, was set off by criticism from Cruz. In response, Trump blamed the mayor’s "poor leadership," suggested that Puerto Ricans officials were "not able to get their workers to help" and said islanders "want everything to be done for them."

The comments were not taken well. Cruz on Sunday declined to respond directly to Trump’s tirade on ABC’s "This Week," but that didn’t stop widespread reporting on the spat.

Los Angeles voters face another special election, this time for the Assembly seat vacated by newly elected Rep. Jimmy Gomez. The primary is Tuesday. If no one receives more than 50% of the vote -- likely, given the crowded field of 13 contenders -- the top two will advance to a runoff scheduled for Dec. 5.

CALIFORNIA HAS TOO MUCH POT

California produced at least 13.5 million pounds of marijuana last year — more than five times as much as the 2.5 million pounds consumed in the state. Where did all that extra pot go?

The answer, experts say, is much of the surplus pot not seized by authorities goes across state lines, often to states that have not legalized marijuana. As the Golden State prepares to allow cannabis sale for recreational use, that surplus has become a potential problem. Patrick McGreevy explains on today's front page.

As Democratic Sen. Dianne Feinstein contemplates a 2018 reelection bid, a new poll found 50% of California’s likely voters think she shouldn’t run again. Just 43% of likely voters support Feinstein seeking a sixth term, according to a Public Policy Institute of California poll released Wednesday. The poll also found that more than half of likely voters approved of the job she’s doing. PPIC President Mark Baldassare said those mixed results are difficult to interpret and at the very least indicate that voters remain restless.

The California Legislature’s Latino caucus endorsed former Los Angeles Mayor Antonio Villaraigosa for governor. While expected, the nod from the politically influential caucus provides a boon to Villaraigosa, a former Democratic Assembly speaker and the only major Latino candidate running for governor, who lags behind front-runner Lt. Gov. Gavin Newsom in the polls and fundraising. What does the endorsement mean for Kevin de León?

California treasurer and candidate for governor John Chiang has pretty much lived off his government paycheck during the last six years.

According to Chiang’s tax returns, his average income from 2011 through 2016 was just over $184,000 a year, including his salary as treasurer, his now-estranged wife’s earnings and some small investments. Chiang and Newsom are the only candidates for governor who have made their tax returns public. Villaraigosa promises to join them soon.
